Hi Andrey,

I'm running lxc (lxc-ls --version 3.0.4).  Here's a stanza from config:

     lxc.net.3.type = veth
     lxc.net.3.link = LAN
     lxc.net.3.flags = up
     lxc.net.3.hwaddr = 00:16:3e:cf:2b:b3

As you can see I set the interface "up" in the config.  All network 
settings (IP, etc) are set within the container.  The bridge it is using 
is predefined in the host before invoking the container.

Hope that clears some things up.
